" Flexible wall containers with dispensers have been used for many purposes. One use of such containers and dispensers has been'in the dairy industry in connection with disease prevention. In that industry one method of disease prevention is carried out by means of teat dipping with a bacterial control solution, particularly forthe prevention of mastitis in dairy cows. The dispensers used for such dipping usually have a well in the upper portion of the dispenser and some means for forcing liquid from the container into the well. In order for such a dispenser to work properly it is necessary that several criteria be met. First, the dispenser must be inexpensive to manufacture in order that it may be provided to the user at a minimum of cost; second, the dispenser must be designed to permit the insertion of the teat into the well quickly and easily so that the dipping operation can be carried out efficiently; and, finally, the dispenser must be designed so that the treating solution will not be easily spilled or lost in transferring it from the container to the dispenser.

Accordingly, it is an object of the present invention to meet each of these criteria. Therefore, the present invention provides a dispenser which has the unique construction of providing adequate space for dipping as well as sure means of conducting the liquid from the container into the well portion of the dispenser.

This is carried out by means of a dispenser which is adapted to be substantially molded as a single piece with only a semi-closure cap added to provide the complete dispenser combination. By the present invention liquid is forced by squeeze pressure from the container through a conduit and then it is directed downwardly along the outer portion of the conduit into a well formed with tapered walls. Thus. it will be seen that the present invention provides a simple arrangement whereby the path of the fluid from the container to the well of the dispenser is controlled and precisely directed at all times.

DESCRIPTION OF THE DRAWINGS:

FIG. 1 is a perspective view of the dispenser and container combination of the present invention;

FIG. 2 is a sectional side view of the dispenser and container combination of the present invention showing a teat inserted into the well of the dispenser; and

FIG. 3 is a partially fragmentary perspective view of the upper portion of the conduit of the dispenser of the present invention.

DESCRIPTION OF THE ILLUSTRATED EMBODIMENT:

Referring to the drawings and to FIGS. 1 and 2 in particular, a container is shown in combination with a dispenser 12. It will be noted that the container 10 which is of the flexible wall type has a low profile. Such a container has an advantage in teat dipping since the container is not cumbersome and it is easily inserted under the udder ofa cow to immerse the teat in the dispensers well.

In the container 10 the dipping liquid 14 is contained and this liquid may be of any desired kind, depending upon the purpose for which it is intended to be used. The container 10 has a bottom wall 16 and flexible side walls 18. At the upper extent of the side walls 18 a shoulder 20 is provided which connects to the neck 22 of the container. The neck 22 which has a series of threads molded on its outer portion, surrounds a wide, open mouth 26.

The dispenser 12 which is shown connected to the container 10 in the illustrated embodiment has an open well 28 on its top surface. Surrounding the well 28 is an annular top wall 30 and depending from this top wall 30 is a skirt 32 which has a plurality of threads 34 on its inner surface. The threads 34 on skirt 32 engage the threads 24 on neck 22 of the container. Thus, the dispenser is readily joined and attached to the container.

The well 28 has an inwardly tapered side wall 36 which joins with a concave bottom wall 38. Integrally molded into the dispenser l2 and extending through the side wall 36 is a conduit 40. The conduit 40 in the illustrated embodiment is aligned substantially vertically with, but eccentrically of, the center longitudinal axis A of the well 28.

The conduit 40 extends from the inner portion of the container 10 and into the well 28. The lower conduit portion 42 extending into the container 10 has connected to it a flexible tube 44 which is of sufficient length to be adjacent to the bottom wall 16.

A continuous bore is provided through the conduit 40.

As shown in FIG. 3 the upper conduit portion 48 has a plurality of recess portions 50 formed on its outer surface and these recessed portions are bounded by a plurality of ribs 52. The rib ends 54 extend beyond the top 56 of the remainder of the upper portion 48. Finally a cap 58 is fitted over the upper portion 48 and embraces the ribs 52. The rib ends 54 space the cap 58 above the top 56, thus, completing a path for the liquid 14 from the interior of the container 10 into the well 28 of the dispenser. This path is through the flexible tube 44 into the bore 46 of conduit 40, over the top 56 and between the ribs 52, the upward travel of the liquid being limited by the upper portion of the cap 58. Because of the particular construction of the conduit 40 and the cap 58, the liquid which is pumped by outside pressure against the flexible walls 18 moves upwardly and then it is deflected downwardly insuring that it will be deposited into the well 28.

In actual operation by merely squeezing the walls 18 any desired quantity of a liquid 14 can be placed in the well 28 along the circuitous path which has been described.

It will be seen that the present invention provides a simple dispenser with a sure means of directing the liquid into the well where it can be used, as shown in the illustrated embodiment for teat dipping.

The flexible wall container may be made of any suitable plastic material such as polyethylene. The dispenser may also be made of any desired plastic material but preferably it is of a rigid or at least a semi-rigid construction.
